About Listmargin
Free eBay fee and profit calculator. No signup, reads the full fee schedule.
Listmargin is a free calculator for eBay sellers. It works out final value fees, ad fees, and what you actually keep on a sale. Most fee calculators copy a four-line summary of eBay's rates; this one reads the full published schedule: all 46 category rates, the store subscription tables, and the categories where the rate changes partway up the price. A weekly monitor checks eBay's published pages so the rates stay current. Free, no signup, no paid tier on the calculator. There's also an embeddable version for blogs and tool sites.
